1. A security system to detect a concealed item carried by a traveler in motion, the security system comprising:

  • a camera configured to capture an image series of the traveler in one of an Eulerian frame of reference and a Lagrangian frame of reference, wherein the captured image series contains motions generated by the concealed item;

    an alarm system that produces an alert signal; and

    an electronic control unit configured to;

    magnify the motions generated by the concealed item to generate frame of reference perceptible motions;

    detect characteristic kinematic behaviors of the perceptible motions;

    measure characteristic kinematic quantities of the characteristic kinematic behaviors;

    determine a presence of the concealed item from the characteristic kinematic quantities; and

    activate the alarm system to produce the alert signal.
